These cards were part of a game I made for my application to HKU for which we had to design a game.
I chose to create a game that was very loosely inspired by rock, paper scissors.
Both players each take 5 cards from their deck, then reveal 1 card and play 1 card.
The players then check which played card wins.
For the numbered cards, the higher number is the one that wins.
For the Letter cards, it gets slightly more complicated. As the P is only beaten by 1, the W is only beaten by 2, the K is only beaten by 4 and the unmarked card.
The K card and the unmarked card represent the player, with the K card represents the player attacking their opponents kingdom, while the unmarked card represents the player defending their kingdom.
